Because it is relatively accessible to scientists, Lake Hawassa is the most studied of the Rift Valley lakes in Ethiopia. According to William Taylor, a member of the African Lakes and Rivers Research Group at the University of Waterloo, Lake Hawassa is, despite its lack of an outflow, "essentially a freshwater lake (conductivity is variable, but less than 1,000) indicating that it must have a subterranean outlet."^[1]
